changing controls on output of tlv320aic3x

HI all,

I was using a OMAP5 based processor board in which the data from processor comes to codec and heads forward to HPLOUT AND HPROUT .....but now i want to change the controls to LEFT_LOP AND RIGHT_LOP... i know we can do it by changing the control register given for it in datasheet but thats not working.....

CAN ANY1 give a quick suggestion over this ,how should i do this change in codec driver file ??? or any other way to take sound out of those two points ???

1. i am getting proper data from host side through serializer pin

2. both snd modules are present . checked it by lsmod

3. Also tried to set controls using amixer sset command but didnt work at all...


any suggestion will be highly appreciated ,... thanks in advance

    Hi, Dusty,

    Unfortunately, we are not familiar with the OMAP5 implementation. I saw you posted in the OMAP forum, too, so I hope that they can help you.

    HI THERE

    but i read that codec driver is always platform independent. also if you see in the codec datasheet ,the codec driver always handles the DATA coming from AXR PIN .... after that how it is being processed in codec depends upon control registers value...

    So there must be some  solution in codec driver itself or may b by changing settings on alsa user space utilities such as alsamixer ,amixer...
